I am guessing your build host is not arm....

Back when gpsd used autoconf, I fixed cross compiling, and it worked
well.  I have not tried since the switch to scons.    Basically, the
notion of building a program and running it is something you just can't
do.

I'm not even really clear on the need to check time_t; it seems to be
about giving warnings to people if time_t is still a 32-bit value (which
is an OS choice, not determined by the CPU type, but one well-known OS
seems to use the native word size).

That build/run should obviously be conditional on not doing cross
compliation, with the usage either skipped or somehow worked around if
so.   I think cross compilation is a requirement (and esr listed it as
so when he posted my requirement list :-), so I'd be inclined to just
remove this if at all possible.

You could try removing this from SConstruct, and either 1) find that the
definition added isn't used or 2) put a definition for your target there
manually.
